摘要 |
An arrangement for monitoring clock frequency variations on a peripheral bus is provided to improve operations of the peripheral device despite changes in the clock frequency. In one aspect of the arrangement, a processing unit is coupled to a host bus which in turn is coupled to a peripheral bus which is coupled to a peripheral device. A monitoring arrangement is provided which detects a change in the clock frequency of the peripheral bus and determines if the frequency change exceeds a threshold associated with the peripheral device. If the threshold is exceeded, the peripheral device is informed that the clock frequency of the peripheral bus has changed. A peripheral device operating a different operating levels may use the information from the monitoring arrangement to alter the operating level of the peripheral device to conform to the new bus clock frequency. |
